Application filed March 12, A1912. Serial 110.683,323.

To all whom 'it may concern Be it known that LXVHLIAM J. HUGHES, alcitinen of the United States of America, residing' at'Victoria, in thecounty of Victoria and State of Texas, have invented certain new anduseful Innirovements in (lombination-qaws, of which the following is aspecification, reference being' had therein to the accompanying drawing.

This invention relates to sawing machines, and the principal objectthereof is to provide a machine in which a planer, a shaper or moldcr, arip ,saw and a cut-oil' saw are operated by a single motor or engine.

In carrying out the objects generally stated above, it will beunderstood, ofcourse,

that the essential features thereof are sus-u ceptible of changes 'indetail and structural arrangements, one `preferred and practicalembodiment ot' the invention being shown in the accompanying drawings,wherein Figure 1 is a side elevation ot' the machine. Fig. 2 is a topplan view of the machine. Fig. 3 is a vertical section through themachine. Fig. i4: is a perspective view of theshaper or melder shaft ormandrel. Fig. 5V is a perspective View of the bracket which holds theplaner knives. Fig. G is a perspective View of one ot' the planerknives. Fig. 7 is a perspective view of one of the knives to be used onthe Shaper or melder head.

Referring to the accompanying drawings by numerals, it Will be seen thatthis invention comprises a base having;r side bars 10 and 11, and endbars 12. A -trame is mounted upon the base and comprises the legs 13 and14, which are connected by cross bars 15 and supports a top or table 16,the top or table being'provided with a longitudinally-extendingslot 17,running' longitudinally with the top plate 1G. A planer mounted in table18 is provided With an opening 19 so that the planing knives canprotrude above the surface of the planing table the desired distance. Amotor 20 is mounted upon the frame at the rear end and a shaft 21 ismounted upon the side bars 10 and 11 in bearings 22, the shaft 21 beingrotated by a belt 23 passing around the pulley wheels 24 and 25 carriedby the shaft 21 and engine shaft 26. A shaft 27 is rotatably bearings 28carried by the side bars 15 and extends beyond the side of the frame andis positioned beneath the open-` ing 19. A bar 429 havingsingularly-disposed ends 30 is secured to the outer end of shaft 27 andknives 31 are removably connected with the ends 30 and have theircutting edges protrlulingn above the face of the planint,r table so thatwhen a piece of'timber is moved along the planing' table, the planingknives will cut the lower face. A pulley wheel 32 is mounted upon theinner portion oi the shaft 27 and a large pulley Wheel 33 is mountedupon the shaftl l21 and is connected with the pulley' wheel 32 by meansof a belt 3ft, thus cansing` the shaft 27 to be rotated at a great dealfaster rate of speed than the shaft 21. A rocking frame has its armsprovided with hinges 36 which are secured to the base or side bars 10and 11, the center of the hinge being placed in line with the center ofshaft 21. The upper ends of the arms are connected by a bearingr 37 inwhich is journaled the shaft 38 having' a rotary saw 39 secured to oneend portion beneath the slot 17 so that when the rockingr frame ismoved, the saw will be brought. up through the slot to cut work placedupon the plate 1G.` This shaft 38 is driven by a belt 40 passing aroundthe pulleys 41 and 42. A tongue 13 which is braced by means of a bar 44is positioned between the arms and affords convenient means forconnecting the operating mechanism with the frame, and also forms abalance weight to assist in returning the saw to it-s normal position.

The operating` mechanism comprises a lever A15 which is secured to thelower portion of the tongue 113 and is braced by means of the bar t6which is connected with the,

upper portion of the rockingr frame. The outer portion of the lever isformed into a foot rest fl-7 so that by placing the foot upon the outerportion of the lever, the frame may be rocked to bringr the saw throughthe slot. When the ioot is removed from the lever, Athe spring 48, whichis connected at one end with the rocking frame and at the other end withthe base, returns the Saw to its normal position. It' it. is desired tohold the saw in a raised position for any length of time, thelatchinglever 1l-9 which is connected with the rocking frame by means otthe chain is moved so that its tooth will engage the rack 51 and thusprevent the spring from returning the saw to its normal position. AShaft 52 "is jonrnaled in the bearings 53 which are secured to a plate54,

than the pulley wheel 55 so that the shaft 52v will be rotated veryrapidly. Clutch collars 58 are mounted upon the outer portion of the lshaft 52 and a cutting knife 59 is secured between the collars by thenut 60. It is, of course, obvious that the knife 59 may be provided withany desired shape of cutting edo'e. Y A

rom the above description, it-will be seen that the motor drives theshaft 21, the shaft 21 drives the shafts 27 and 38,- and the shaft 27drives the 'shaft 52.

What I claim is In a sawing machine, a table provided with a slot in itstop, a swinging frame, strips carried by saidswinging frame andpivo'tally connected with the side of said table to pivotally mount saidswinging frame, a driving shaft journaled upon the sides of said table:beneath said swinging frame, a saw journaled in the upper portion ofsaid swinging frame androtated by y said driving shaft, adependingtongue carried by sald swinging frame, a spring having one end connectedwith said table and the upper end with said tongue to normally hold saldsaw beneath the top of said table,

a foot lever rigidly mounted upon saidl In testimony whereof I hereunto.aiiix myA signature in presence of two witnesses.
